Description

TECHNICAL FIELD [0001] The present invention relates to an acoustic haptic-based active alert and convenience service-based next generation seat interface system,

The present invention relates to a seat interface system, and more particularly to a next generation seat interface system for acoustic haptic-based active alert and convenience service.

The vehicle is heavily influenced by the external environment during operation. For example, there are many external environments that could pose a risk to the driver, such as obstacles around the vehicle, lane departure. However, there has been a lot of risk since the driver must judge all information by sight. To solve this problem, in recent years, techniques have been developed to give information to the driver by the vibration of the steering wheel and the seat. However, for this purpose, a vibration generating device should be used, and a vibration motor was used in the past. These conventional vibration motors control the motor by the pulse width modulation signal, and the motor generates vibration by rotation. However, since a vibration motor that generates vibration by rotation is used in the past, there is a problem that the entire seat on which the motor is installed is not able to grasp the origin of the vibration when the motor vibrates. That is, in the past, only the presence or absence of vibration could be expressed, and there was a limit in transmitting various information using vibration.

FIG. 3 is a perspective view illustrating a vibrator position of an acoustic haptic-based active warning and convenience service next generation seat interface system according to the present invention.

The vibrator 3000 is built in the seat and vibrates in accordance with the vibration signal output from the amplifier 2000. This embodiment exemplifies four vibrators with this vibrator 3000 and four vibrators 3000 include a first vibrator 3100 and a second vibrator 3200, a third vibrator 3300 and a fourth vibrator 3400 ). Further, each vibrator 3000 exemplifies that the vibrator 3000 is provided in the seat and the back of the seat. Accordingly, the present embodiment illustrates that the first vibrator 3100 and the second vibrator 3200 are provided in the seat seat, and the third vibrator 3300 and the fourth vibrator 3400 are provided in the seat back. The present embodiment exemplifies a seat seat left vibrator provided on the left side of the seat seat by the first vibrator 3100 and a seat seat right side vibrator provided on the right side of the seat seat by the second vibrator 3200. [ Also, a seat back left vibrator provided on the left side of the seat back by the third vibrator 3300 and a seat back right side vibrator provided on the right side of the seat back by the fourth vibrator 3400 are illustrated. Of course, the vibrator 3000 may be provided in less than four or more than four vibrators. Further, the vibrator 3000 of the present embodiment may be provided either in the seat seat or in the seat back. The vibrator 3000 may include a sound actuator. The conventional vibration motor generates vibration by rotation of the motor. However, the present invention can transmit various information through vibration by using a sound actuator that generates vibration by vertical motion.

4 and 5 are diagrams illustrating vibrations of a vibrator according to modes of an acoustic haptic-based active warning and convenience service next generation seat interface system according to the present invention.

In the active warning mode, the acoustic haptic-based active warning and convenience service next generation seat interface system according to the present invention having the above-described structure vibrates the vibrator according to the active warning signal of the vehicle inputted through the signal input module 130. For example, in the case of a lane departure warning, the left seat vibrator vibrates when the vehicle leaves the left lane, and the left side vibrator vibrates when the vehicle leaves the right lane. Further, in the case of a frontal collision warning, the left seat vibrator and the right seat vibrator are simultaneously vibrated. Front car departure announcement also vibrates both seat seat left vibrator and seat seat right vibrator at the same time. At this time, in order to make a difference between the frontal collision warning and the frontal vehicle departure notification, the vibrator is vibrated so that the strength of the frontal collision alarm is stronger than that of the frontal vehicle, and the duration is longer.

When an obstacle is detected from the front and rear of the vehicle by the front sensor and the rear sensor, the vibrator in the direction in which the obstacle is located is vibrated. Here, the present invention increases the vibration intensity of the vibrator as the obstacle approaches the vehicle. In addition, a plurality of vibrators can be simultaneously vibrated to precisely recognize the position of the obstacle. This can be done by increasing the strength of the vibrator in the direction in which the obstacle is present. For example, as shown in Fig. 4 (a), when the obstacle is located on the front left side of the vehicle, only the seat seat left vibrator is vibrated. 5 (b), if the obstacle is slightly shifted to the right from the front of the vehicle and is shifted to the left from the center of the vehicle front, the seat seat left vibrator and the seat seat right side vibrator are simultaneously vibrated, Seat seat Left vibrator is made to vibrate more strongly than seat seat right vibrator. That is, the vibration intensity of the vibrator changes in real time according to the movement of the obstacle, so that the occupant can accurately grasp the direction of the obstacle in the vehicle and the direction in which the obstacle is moving.

In the case of the traffic information collecting device, the vibrator is vibrated according to the traffic situation in the vicinity of the vehicle, particularly in the vehicle traveling direction, so that the driver can recognize the traffic situation ahead by vibration. For example, when an accident occurs in the front, the left seat vibrator and the right seat vibrator can be vibrated three times in less than one second. Also, when the front traffic is stalled, the vibrator on the left side of the seat seat and the seat side on the right side vibrator can be vibrated 5 times within 1 second, and then the entire vibrator can be vibrated twice within 1 second. Of course, such a vibration pattern can be applied variously.

On the other hand, the various vibration patterns described above are stored in advance in the sound generator 1000 or the amplifier 2000, or can be set by the driver. At this time, when the driver sets the vibration pattern, it can be performed through the display connected to the display control module 150 or the display control module 150. For example, the position of the vibrator included in the seat shape and the seat is displayed on the display control module 150 or the display, and the driver can select a vibration pattern setting mode on the display and then touch the displayed vibrator . For example, when setting the vibration pattern when the front traffic is stagnated, it is possible to set which vibrator is to be vibrated by touching the vibration pattern setting button of the corresponding mode, touching the displayed vibrator or dragging a plurality of vibrators. Of course, it is also possible to set how many times the vibrator vibrates within a certain time. Furthermore, since the vibration pattern set by the user may be overlapped for each mode, it is preferable to compare the stored vibration pattern with the inputted vibration pattern and display it on the display when they overlap.

The music sheet mode vibrates the vibrator according to the bass of the music input through the audio input terminal 210, the sound source module 220, the Bluetooth module 230, and the like. In this case, the inputted music is leveled through the level equalization module 240 and output to the output terminal through the selection module 250. [ At this time, the selection module 250 selects the audio input terminal 210, the sound source module 220, or the Bluetooth module 230 to which music is input, so that music can be output. Also, the music output through the output terminal is input to the amplifier module 2100 through the input terminal of the amplifier 2000 section. The amplifier module 2100 generates a vibration signal by passing only a low frequency band of less than 200 Hz in the input music, and the vibration signal generated by the amplifier module 2100 is outputted to the vibrator so that the vibrator vibrates according to the vibration signal. Accordingly, the music sheet mode causes the vibrator to vibrate so as to correspond to the low frequency of the music, so that the occupant seated on the seat can feel the bass of the music through the vibration.

The sound therapy mode allows the vibrator to generate vibration corresponding to bass on the basis of the sound source stored in the sound source storage module 221, so that the passenger can be stably and healed. To this end, the sound source stored in the sound source storage module 221 is reproduced by the speaker of the vehicle, and the vibrator vibrates in correspondence with the bass of the sound source reproduced by the speaker of the vehicle. Here, the sound source may include a sound of rain, a sound of wind, a sound of a stream, and the like. The sound source may be input from an external device through the audio input module, the Bluetooth module 230, and the like.

The massage mode vibrates the vibrator based on the sound source stored in the sound source storage module 221, thereby massaging the passenger's back, back, and buttocks. This can be performed through a sound source stored in the sound source storage module 221. However, the present invention is not limited to this, and a massage mode may be performed by an external sound source. For example, the massage mode may be performed in accordance with the music input through the audio input terminal 210 or the Bluetooth module 230. In this case, it is effective that the amplifier module 2100 increases the intensity of the vibrator by increasing the level of the input sound source in order to increase the massage effect.

The navigation mode activates the vibrator according to the navigation information output from the navigation system. To this end, the navigation system is connected to the sound generator 1000, and the sound generator 1000 selects navigation information output from the navigation system and transmits the navigation information to the amplifier 2000. The amplifier 2000 receives the vibration signal corresponding to the navigation information And outputs it to the vibrator. Here, the present invention may include more vibrators to more intuitively transmit navigation information. In this case, as shown in FIG. 5, left or right oscillation can be given at the branch road, and left turn, right turn, U-turn, and overspeed alarm can be displayed. More specifically, referring to FIG. 5, the vibrator is operated according to the navigation information output from navigation, and vibrates the seat-seat front vibrator in the seat-seat right vibrator when the navigation information is left-turned, And vibrates the seat seat left vibrator when the navigation information is the left side at the forking road and vibrates the seat seat right side vibrator when the navigation information is right side at the forking road, When the information is U-turn, you can vibrate in the order of seat seat right vibrator, seat seat front vibrator and seat seat left vibrator in this order.

As described above, the present invention converts a sound source of a sound generator into a vibration signal through a multi-channel amplifier and operates the vibrator to accurately transmit various information such as navigation information, position of an obstacle, lane warning, traffic information, have. Further, according to the present invention, the origin of vibration can be accurately grasped by using a vibrator that generates vibration by vertical motion, and the driver can transmit various information by vibration to the driver without confirming the instrument panel. Further, in the music sheet mode and the sound therapy mode in which sound and vibration are generated together, the occupant can feel the bass of music or recover the fatigue of the occupant. In addition, the present invention can embody a sound generator, an amplifier, and a vibrator in a seat, and realize functions related to the vibration of the seat alone by using only one seat.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. You will understand.
